Particle shape and surface roughness affect both the macro- and micro-mechanical behaviour of natural sands. In geotechnical practice, the global shape of sands is generally characterized by visual comparison to reference charts or by static image analysis with a limited number of particles. Meanwhile, due to the difficulty in measuring …

In conclusion, geotechnical laboratory experiments quantified the important impact of the elliptic, plate-like shape of Advocate Beach sand on the angles of internal friction of both pure sand and sand–gravel mixtures. The resulting effect on initiation of particle motion was confirmed in tilting tray experiments.

The effects of particle shape and size distribution on the constitutive behavior of composite soils with a wide range of particle size were investigated. Two comparable sets of specimens were prepared: (1) mixtures of fines (clay and silt) and an ideal coarse fraction (glass sand and beads), and (2) mixtures of fines and natural …

Extra aeration should be completed if the bunker sand is finer than the rootzone sand. Sand that is too coarse—over 2 mm—should also be avoided since it can cause damage to mowing equipment. Particle Shape and Penetrometer Value. Shape is determined by its angularity and sphericity—in other words, how sharp and round it is.

Therefore, Jiang et al. classified gravel particle shapes into four types, namely, spherical, ellipse, cone, and disk, through classification statistics. The distribution of gravel particle shapes is shown in Table 1. The shape of the sand was simplified to a spherical shape due to the inability to accurately count the sand of various shapes ...
